AbstractElectric vehicles, hybrid electric vehicles, and plugin hybrid electric vehicles (EVs, HEVs, and PHEVs) are emerging technologies that can significantly reduce petroleum usage in the transportation sector. Widespread adoption of electricdrive vehicles will lower automobile operation costs and can significantly decrease emissions of greenhouse gases. However, for these technologies to be successful in todays market, a new generation of batteries with improved cost per kilowatthour is needed. Yardney Technical Products, Inc. (YTP), a world leader in advanced battery systems for specialty applications, proposes to develop a transformational battery design that will decrease weight and cost significantly. The proposed concept involves drastic design advancements that will eliminate a large portion of the inactive weight present in all stateoftheart lithiumion (Liion) cells. Additionally, high capacity anode materials with 3 times the specific capacity of commercial graphites will be used to further increase specific energy and energy density. Batteries which incorporate the proposed innovations will weigh 2030% less than stateoftheart technologies at the cell level.
